Things you can do with unused t-shirts.
There's always that free t-shirt giveaways or you don't wear anymore.
I used them to make into yarn and crochet them into rug. I bought 5 drawers from IKEA to put into my studio but I didn't want to damage my wooden floor. It was hard to find exact rug size I want and it took a while but I choose to crochet my own rug that fits just right!
I started with making a t-shirt into strips and spool into a ball. The
best fabric to use is an old bed sheets! That makes lot of yarn!
My studio is still a mess to show yet, but hopefully in the winter I can spend time to decorate the place the way I want it.
